Mercury Magnetospheric Orbiter, top view

MERCURY MAGNETOSPHERIC ORBITER

JAXA's Mercury Magnetospheric Orbiter (MMO) is a spin-stabilised spacecraft that will make 15 rotations per minute, with its spin axis 90º to the Sun. It will operate from a 9.3 hour elliptical polar orbit, that will take it between 590 and 11 640 km above the planet's surface.

Because it won't be spinning during the journey, it will be protected by the MMO Sunshield and Interface Structure (MOSIF). This ESA-built component will not only provide thermal protection but also mechanical and electrical interfaces for the MMO, before it is discarded after arriving at Mercury.

The MMO has five science instruments:


MMO's science instruments

Mercury Magnetometer (MMO-MAG): Providing a detailed description of Mercury's magnetosphere and of its interaction with the planetary magnetic field and the solar wind. Principal Investigator:Wolfgang Baumjohann, Austrian Space Science, Graz, Austria.

Mercury Plasma Particle Experiment (MPPE): Seven sensors studying plasma and energetic particles in the magnetosphere and the interaction between the solar wind and Mercury's magnetosphere. Principal Investigator: Yoshifumi Saito, Institute of Space and Astronautical Science, Kanagawa, Japan.

Mercury Plasma Wave Instrument (PWI): In situ and remote-sensing analysis of electric fields, plasma waves and radio waves in Mercury's plasma environment. Principal Investigator: Yasumasa Kasaba, Tohoku University, Sendai, Japan.

Mercury Sodium Atmosphere Spectral Imager (MSASI): Measuring the abundance, distribution and dynamics of sodium in Mercury's exosphere to investigate its sources and related processes. Principal Investigator: Ichiro Yoshikawa, University of Tokyo, Japan.

Mercury Dust Monitor (MDM): Studying the distribution of interplanetary dust in the orbit of Mercury. Principal Investigator: Masanori Kobayashi, Chiba Institute of Technology, Japan.

HIGH TEMPERATURE CHALLENGE

Most of ESA's previous interplanetary missions have been to relatively cold parts of the Solar System. BepiColombo will be the Agency's first experience of sending a planetary probe close to the Sun. At Mercury it will endure temperatures in excess of 350°C. To cope with this, the spacecraft's external items, such as the antennas, solar arrays, Sun sensors and multilayer insulation, have temperature-resistant outer layers and protective coatings, which were individually qualified to prove their capability.

Despite travelling towards the Sun, the transfer module requires a large solar array, its two wings together totaling 42 m2. Because of the high solar intensity, they cannot directly face the Sun without reaching excessively high temperatures, so they instead have to be rotated away from the Sun and therefore still need a large area to meet the power requirements of the spacecraft.


BepiColombo in cruise configuration

The Mercury Planetary Orbiter is a three-axis stabilised spacecraft with one side facing Mercury. It is equipped with a radiator of the largest size compatible with the Ariane 5 fairing diameter. This is specially designed to reflect heat directionally, thus allowing the spacecraft to fly at low altitude over the hot surface of the planet. Heat generated by spacecraft subsystems and payload components, as well as heat coming from the Sun and Mercury and 'leaking' through the blankets into the spacecraft, is carried away to the radiator by heat pipes.

Most science instruments are mounted on the side of the spacecraft pointing at Mercury, with certain instruments or sensors located directly at the main radiator, to achieve the low detector temperatures needed for sensitive observations.


BepiColombo stack

The Mercury Magnetosphere Orbiter is an octagonal spin-stabilised spacecraft; its spin axis will be nearly perpendicular to Mercury's orbital plane around the Sun, ensuring that the 'top' and 'bottom' of the spacecraft are never Sun-pointed. Each of the eight side panels is fitted with solar cells, with the areas not covered equipped instead with a mirror finish to reflect solar radiation. The spinning nature of the craft also helps to evenly distribute the heat, like roasting a pig on a spit.

Because it will not be spinning during the cruise phase, it is thermally protected by the sunshield for the journey.

Early birth and strange chemistry: Mercury studies reveal an intriguing target for BepiColombo

A month before the planned launch of the joint ESA-JAXA BepiColombo mission to Mercury, two new studies shed light on when the innermost planet formed and the puzzle of its chemical composition. The findings will be presented by Bastien Brugger and Thomas Ronnet at the European Planetary Science Congress (EPSC) 2018 in Berlin.

Mercury is the least-studied of the terrestrial planets and is something of an anomaly compared to Venus, Earth and Mars. It is very small, very dense, has an oversized molten core, and formed under chemical conditions that mean it contains much less oxidized material than its neighbouring planets.

Research by a team at the University of Aix Marseille suggests that two factors may help explain why Mercury is so strange. Firstly, the planet may have formed very early in the Solar System's history fr om condensed vapour from planetesimals. Secondly, the distribution of sulphur and silicon within Mercury's mantle and iron core may be different than previously thought.

Спойлер

"We think that very early in the Solar System, planetesimals in the innermost region of the Solar System could have formed from reprocessed material that was vaporized due to the extreme temperature there and subsequently recondensed," said Ronnet. "In addition, we are able to rule out a scenario wh ere Mercury formed from a pile-up of planetesimals coming from further out in the Solar System since, in this case, Mercury would contain more oxidized material than we actually find."

Previous studies have suggested that Mercury is very rich in iron, but contains more sulphur than should be available in the material from which the bulk of the Solar System formed.

Brugger ran computer simulations of Mercury's interior with a large range of densities and compositions and compared the results with gravity data gathered by the MESSENGER mission.

"We found that silicon may be the key alloying element in Mercury's core, instead of sulphur, the previous main suspect," said Brugger. "By having a much richer silicon content in the core and less sulphur, our models matched both the MESSENGER observations and the latest laboratory experiments on the composition of Mercury. This could solve the problem of why Mercury seemed to have too much sulphur compared to the rest of the Solar System."

The results also suggest that Mercury has a dense mantle that may contain substantial amounts of iron. To confirm this, Brugger and his colleagues will need further observations from future missions.

"MESSENGER did not detect iron in its analysis of Mercury's surface composition, but this may be due to the spectral channels of its instrumentation. With the launch of BepiColombo, we will have a whole new suite of instruments to investigate this mysterious planet and try to understand its structure and origins," said Brugger.

BepiColombo is Europe's first mission to Mercury. It is a joint endeavour between ESA and the Japan Aerospace Exploration Agency, JAXA, and consists of two scientific orbiters: ESA's Mercury Planetary Orbiter and JAXA's Mercury Magnetospheric Orbiter. They will be carried on a seven year journey to the innermost planet by the Mercury Transfer Module, using a combination of ion propulsion and gravity assist flybys at Earth, Venus and Mercury. The mission will study all aspects of Mercury, building on the achievements of MESSENGER to provide the best understanding of the Solar System's innermost planet to date.

• Title BepiColombo stack
• Released 26/09/2018 2:00 pm
• Copyright ESA–B.Guillaume
• Description
  
  The BepiColombo spacecraft 'stack' is complete. ESA's Mercury Transfer Module sits at the bottom, its two 15 m-long solar arrays folded for launch. It will use a combination of solar electric propulsion, chemical propulsion, and nine gravity assist flybys over seven years to deliver the two science orbiters that sit above, to Mercury.
  
  In the middle of the stack is ESA's Mercury Planetary Orbiter, its 3.7 m wide radiator facing the viewer. The three red oval shapes indicate startrackers, which will be used for navigation.
  
  Most science instruments are mounted on the side of the spacecraft that will point at Mercury – the side clamped against the transfer module during cruise – but some instruments and sensors are located at the main radiator, and the magnetometer boom is folded above.
  
  On top is JAXA's eight-sided Mercury Magnetospheric Orbiter. The sunshield that will protect the module during the cruise phase will be added about a week before launch.
  
  Eight of the 11 instrument suites onboard the Mercury Planetary Orbiter and three out of five on the Mercury Magnetospheric Orbiter can operate or partially operate during the cruise phase, and will take measurements during the two flybys of Venus, for example. Once at Mercury, the two orbiters will operate from different orbits to provide the most detailed study of the innermost planet date, from its interior to surface features, to its interaction with the solar wind.
  
  The complete spacecraft stack will be attached to the launch vehicle and sealed inside the fairing in the final week before launch. Roll-out of the Ariane 5 to the launch pad is anticipated about two days before launch.
  
  Launch is currently scheduled for 19 October 22:45 GFT local time, or 01:45 GMT / 03:45 CEST on 20 October. It will be the 101st launch of an Ariane 5.
  
  Details on how to follow online will be provided closer to the day.

Ariane 5 | October 2, 2018
BepiColombo is readied for its October 19 Ariane 5 flight on a mission to Mercury


The two BepiColombo science orbiters are assembled during activity in the Spaceport's S5 payload preparation facility, marking an integration milestone in preparation for Arianespace's October 19 launch with an Ariane 5.

Preparations are moving ahead for Arianespace's next Ariane 5 launch, which will send the BepiColombo spacecraft on its way to the solar system's smallest and least-explored terrestrial planet: Mercury.

Scheduled for an October 19 liftoff from the Spaceport in French Guiana, this upcoming flight will continue Arianespace's launch services for missions that help unlock mysteries of deep space.

Спойлер

BepiColombo is a joint mission of the European Space Agency and the Japan Aerospace Exploration Agency. Its Mercury Composite Spacecraft (MCS) consists of two orbiters: the Mercury Magnetospheric Orbiter (MMO) and the Mercury Planetary Orbiter (MPO); as well as two additional elements: the Mercury Transfer Module (MTM), and the Magnetospheric Orbiter Sunshield and Interface Structure (MOSIF). BepiColombo was built under the industrial leadership of Airbus, which heads a consortium of 83 companies from 16 countries.

After launch by Ariane 5, BepiColombo will arrive at Mercury in late 2025. During its one-year nominal mission (with a possible 1-year extension), the MPO and MMO will examine the peculiarities of Mercury's internal structure and magnetic field generation, as well as how the planet interacts with the sun and solar wind. Goals of the mission also include investigating Mercury's surface features and chemistry.

Designated Flight VA245 in Arianespace's launcher family numbering system, the BepiColombo mission will be the company's seventh in 2018, following heavy-lift Ariane 5 flights in September, July, April and January; as well as a light-lift Vega launch in August and a medium-lift Soyuz mission in March.

N° 24–2018: CALL FOR MEDIA: BEPICOLOMBO LAUNCH TO MERCURY

8 October 2018

The BepiColombo mission to Mercury is scheduled to launch aboard an Ariane 5 from Europe's Spaceport in Kourou, French Guiana at 01:45 GMT (03:45 CEST) on 20 October 2018. Representatives of traditional and social media are invited to apply for accreditation to follow the launch live from ESA's mission control centre in Darmstadt, Germany.

BepiColombo is a joint endeavour between ESA and the Japan Aerospace Exploration Agency, JAXA. It is the first European mission to Mercury, the smallest and least explored planet in the inner Solar System, and the first to send two spacecraft to make complementary measurements of the planet's dynamic environment at the same time.

Спойлер

It will build on the discoveries and questions raised by NASA's Messenger mission, which orbited the planet between 2011 and 2015, to provide the best understanding of the Solar System's innermost planet to date. BepiColombo will provide information about solar system evolution in general – not just about our own, but regarding how planets orbiting close to their stars in exoplanet systems form and evolve, too.

The mission comprises two science orbiters: ESA's Mercury Planetary Orbiter (MPO, or 'Bepi') and JAXA's Mercury Magnetospheric Orbiter (MMO, or 'Mio'). The ESA-built Mercury Transfer Module (MTM) will carry the orbiters to Mercury using a combination of solar electric propulsion and gravity assist flybys. In an ambitious seven-year flight, the mission will make one flyby of Earth, two at Venus, and six at Mercury, before entering orbit.

A big challenge for the mission is the Sun's enormous gravity, which makes it difficult to place a spacecraft into a stable orbit around Mercury – even more energy is needed than when sending a mission to Pluto. After launch, and having escaped the 'gravity well' of Earth, BepiColombo must constantly brake against the gravitational pull of the Sun. Ion thrusters on the MTM will provide the needed low thrust over long durations of the cruise phase, and employs technology demonstrated previously in ESA's GOCE mission to study Earth's gravity and in the SMART-1 mission to the Moon.

The high solar intensity experienced during the journey and later during operations at Mercury also demanded new technologies to be developed – such as high-temperature coatings and multi-layered insulation, a radiator for the MPO, and a novel spin-technique for Mio – to avoid overheating. During the cruise phase, however, Mio will not be spinning, so it is protected by a sunshield.

The orbiters will be able to operate some of their instruments during the cruise phase, affording unique opportunities to collect scientifically valuable data at Venus, for example. While it will not be possible to use the scientific camera on the journey, three monitoring cameras fixed to the MTM will provide visual confirmation of the successful deployments of the solar arrays and antennas following launch, as well as snapshots during the planetary flybys.

Experts will present the mission, its challenges and scientific goals during a dedicated programme for media at ESOC, which will include viewing the webcast from the launch site in Kourou.
